Help / Suggestions needed : "optimal" settings for LG 27GL63T monitor

[Ariortega]

Hello friends and readers,

again I'm in need of some help / suggestions. So I've got myself a new gaming monitor, the LG 27GL63T , which is FHD (1920 x 1080) @ 144Hz, has an IPS panel, has Freesync and is "G-Sync compatible" (what ever that means).

I found a guy on youtube, who showed in his video what to do in the nvidia control center in order to have the "smoothest / best" gaming experience. Well, that didn't work for me.

Is it helpful to cap the FPS in the control panel to match the monitor's Hz? Is it advisable to turn on V-Sync (and if yes, in the control panel or the game itself) ?


I would really - seriously - appreciate every helpful comment / suggestion, so I can enjoy my games on my new gaming monitor.

edit: forgot to mention my specs: i5-9400f @ 3.9GHz, 32GB DDR4 @ 3200MHz, RTX 2060 Super

Go into the monitor OSD and ensure adaptive sync is enabled, and cap frame rate to 144.

G-sync compatible means you can use adaptive sync with an Nvidia card but there is no g-sync module for variable overdrive. These kinds of monitors usually have an overdrive setting tuned for the max refresh rate and another for 60hz, so you'll need to switch between them depending on the game your playing for the best experience.

ok, so I'll enable adaptive sync. (has 3 options : off, on and "advanced"). Then I'll cap the frame rate in the nvidia control panel to 144. Should I also turn V-Sync on or leave it completely off?

I think on, there's some dark magic where "v sync" means two different things whether g-sync is on or off.

With adpative syncs, you cap the FPS ~3 below what your limit is, otherwise you may over-extend past that, and drop sync for a moment, causing a stutter.

It's up to you;
With it on, you'll never experience tearing, but you will have a slight increase in input latency.
With it off, you may get tearing if the framerates are all over the place, but won't have an increase in latency (except for the stuff that Free/G-sync adds, which you won't feel.)

And, you're using the NVCP's frame limiter, so you don't need RTSS (Since it does the same thing - Though, I prefer RTSS for ease of use.)
So that'll smooth out your frametimes, and since you're using an adaptive sync monitor, you'll want to cap it at a stable Average, or lower point of your FPS, to stop any changes in frametimes (Since if you set it to high, your FPS will constantly be hitting the limit, and dropping, and hitting the limit, and dropping, causing microstutter/latency differences.)

Oh, and make sure you've got your refresh rate set to 144hz in NVCP.

Autumn is 100% correct on all of this. I watched a few videos by Battle Nonsense (dude really knows his stuff) and he pretty much said all of this too.

To summarize;
Enable G-Sync, make sure it's also enabled under 3d settings
Under 3d settings make sure the preferred refresh rate is set to highest available
Enable V-Sync in NVCP (this helps get rid of additional tearing that happens at the bottom of the screen with just G-Sync enabled)
Set the FPS limit a few frames below your fresh rate (generally check to do this in-game first, but if the in game fps limiter is not flexible, do it in NVCP)

This set up gives you the best results for image quality and low input lag.

VSync always means one thing and one thing only - locking the front buffer during the frame scan to eliminate tearing.

OP, follow Autumn's advice, I wouldn't say better myself.
